Abstract
We show how a general description of microstructural changes in a macroscopically rigid conductor implies finite-speed propagation of temperature variations. In this way, we interpret once again Fourier’s paradox as a result of an insufficient representation of the structure of matter. The result is independent of the type of the material microstructure, provided that its changes are influenced by temperature variations. With the present treatment, we indicate a possible view on an old problem, already analyzed from different perspectives.
